The same free speech that is protecting racists today is the same one that prevented Gay people from being censored in the 90s for their "deviant" behavior.
Is your statement intended to be ironic? Gay people were heavily censored in the early 90s outside of cities like San Francisco and West Hollywood. It wasn't until Will and Grace premiered in 1998 that the needle began moving toward acceptance.
Free speech protects the expression of ideas, no matter how disagreeable or vile some demographics may find them. And LGBT ideology was certainly viewed as vile by the majority of the population for many decades and would have been completely stomped out from discourse if not for free speech protections. Want to see what would have happened to the LGBT community without strong free speech protection? Look no further than Russia.
The necessary cost of free speech is allowing speech one disagrees with. People who enjoy the benefits of free speech but fail to understand this core tenet boggle my mind.
